[RFC v0 2/8] selftests: firmware: do not clutter output

[Daniel Wagner <wagi@monom.org>]

From: Daniel Wagner <daniel.wagner@bmw-carit.de>

Some of the test are supposed to fail but we get a few ouptput lines:

./fw_filesystem.sh: line 51: printf: write error: Invalid argument
./fw_filesystem.sh: line 56: printf: write error: No such device
./fw_filesystem.sh: line 62: echo: write error: No such file or directory

Let's silence them so that the selftest output is clean if all is fine.
